A lot has been written about how to tell if a guy has a big dick, and as far as I know, most if not all of the myths have been debunked. Big feet/hands? Nope. Black guy? Nope. Has that BDE? Nope. I’m sure people have anecdotal evidence that points to the contrary, but the sample size on those is likely small.

But what about the other side of the coin?

I’ve run into plenty of women who talk a big game about how they’re size queens, and that the last guy they fucked was hung like John Holmes, and they can’t get off with anything smaller than 8”. However results have varied widely.

My half-assed internet research has proven pretty inconclusive as well. This paper by Jillian Lloyd, https://www.ncbi.nlm.nih.gov/pubmed/15842291 , concluded “ There was no statistically significant association with age, parity, ethnicity, hormonal use or history of sexual activity.” However her sample size was only 50, which is lacking.

Megan O. Schimpf showed that “sexually active women had longer vaginas than women who were not active (9.1 cm ± 1.2 versus 8.9 cm ± 1.3, p = 0.04), significance was explained by age differences.” and enrolled 505 women https://www.ncbi.nlm.nih.gov/pmc/articles/PMC289322… .

Nothing in these data suggests that women were aroused at the time of measurement, so it’s probably safe to assume that unless they had some weird fetish regarding lab work (if you do, let’s talk) they were unaroused. Again, my half-assed internet research shows arguments on both sides. And unless somebody has really dug in on this and knows where there has been good research done, I’m not sure if this question has been answered.

That being said, I’m going to throw this to you all. What are your experiences? I have a pet theory that vaginal size (as well as the size of all the other body parts) increases with height. But my evidence only goes so far. More research is definitely needed.
